TO ALL WHOM IT MAY CONCERN:

Be it known that I, JULES FOUGERAT, of the city, county, and State of New York, have inven. ad a new and improved Process for Prodnci'ng I odine from Mussels, and I do hereby declare that the following is a fiill, clear, and exact description thereof, which, wilienable others skilled -in the art to understand the same.

This invention relates to a new manner ofextracting iodine from mussels, or their shells, and it consists in the following process, by'whichthe crystallized iodine is produced:

The mussels, whether simply shells or when alive, are first calcinized, and are then pulverized. They are then placed into water, about one part of the mussels to five parts of water, and are then boiled until the water stands-abont 36 in the alkalimeter.

Sulphuric acid and protoxide ofiion are'then added to the mixture, insnflicient quantities to dissolve the crystals of the. iodine, v vhich are then precipitated by. means of-a clirrent of chlorine gas, or by sulphide of carbon, end the iodine settles; then, on the bottom of the vessel, in form of crystals:

The protoxide of iron may be omitted, if'desiredf' V As the iodine on the bottom of the vessel may not be quite pure, itshould be redistilled in a retort, 'to, have the pure iodine evaporated, and then condensed in a suitable receptacle.

Having thus-described my invention, what I claim as new, and desire to secure by. Letters Patent, is- 1. Producing iodinefrom' mnssels, as set forth. i r 2. The process herein's'nown and described of producing iodine from mussels.

The above specificationof my invention signed by me, this 16th dey of January, 1868 l J. FOUGERAT. Witnesses:
